1-4 Installing the Memory

DualChannelMemoryConguration

This motherboard provides two DDR3 memory sockets and supports Dual Channel Technology. After the memory

isinstalled,theBIOSwillautomaticallydetectthespecicationsandcapacityofthememory.EnablingDual

Channel memory mode will double the original memory bandwidth.

The two DDR3 memory sockets are divided into two channels and each channel has one memory socket as

following:

Channel 0: DDR3_1

Channel 1: DDR3_2

DDR3_1

DDR3_2

Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.

1. Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.

2. When enabling Dual Channel mode with two memory modules, it is recommended that memory of

the same capacity, brand, speed, and chips be used for optimum performance.

Read the following guidelines before you begin to install the memory:

• Make sure that the motherboard supports the memory. It is recommended that memory of the

same capacity, brand, speed, and chips be used.

(Go to GIGABYTE's website for the latest supported memory speeds and memory modules.)

• Always turn off the computer and unplug the power cord from the power outlet before installing the

memory to prevent hardware damage.

• Memory modules have a foolproof design. A memory module can be installed in only one direction.

If you are unable to insert the memory, switch the direction.

system.

• @BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the Internet

and updates the BIOS.

• It is recommended that you not alter the default settings (unless you need to) to prevent system

instability or other unexpected results. Inadequately altering the settings may result in system's

failure to boot. If this occurs, try to clear the CMOS values and reset the board to default values.
